in a needle of the nsnal type, there is a gradual distention of thestitch from the time the base of the latch enters the same until thestitch is slipped over the hook, and not only is the stitch theeehystrained but the power required to retract the needle grednallj;increases during this portion of its movement.. l. nd that thisdisadvantage of the ordinary latch needle can be overcome by importing aforward inclination to the rear face of the upper portion of the needlestem or shank, such inclination extending Vl`rn the hase of the latch tothe hook, as ,-1 for instance, at 4 in Fig. 2, the angle presented bythis portion of the back of the Specification of etters needle stein, hypretore that presented by the latch, so thet the widen ai end of thelatch and ocres little, if an;Y greater.L tl shank et the il Otel ponn aforward inclination ot the in; the needle stein or shank o mation ot' asmell hooi; and point of the hook in i as that the larger hooi; c t yneeine, and thereby ins agement of the knitting` u it in the ordinaryoperation the in:
